Security SummaryAI

CVE-2025-51958 is a critical vulnerability in the aelsantex runcommand plugin version 2014-04-01 for DokuWiki, enabling unauthenticated attackers to execute arbitrary system commands. The flaw resides in the lib/plugins/runcommand/postaction.php file and is classified as CWE-78 (OS Command Injection). It received a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for remote exploitation without privileges or user interaction.

Any unauthenticated attacker with network access to a vulnerable DokuWiki instance running this plugin can exploit the issue remotely. Exploitation involves sending crafted requests to the postaction.php endpoint, resulting in arbitrary command execution on the underlying server with the privileges of the web server process. This grants attackers high-impact control over confidentiality, integrity, and availability, potentially leading to full system compromise.
